> Key: SLING-9417
> URL: https://issues.apache.org/jira/browse/SLING-9417
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Reporter: Matthias Herold
> Assignee: Robert Munteanu
> Priority: Minor
> Fix For: JCR Resource 3.0.22
>
> Original Estimate: 1h
> Time Spent: 4h 50m
> Remaining Estimate: 0h
>
> When using the methods resource.getMetadata().getContentType() or
> resource.adaptTo(InputStream.class), both methods return null when:
> # the resource is a child of a versionable node,
> # the resource is of type nt:file, and
> # resource has been looked up with a version identifier in the URL (";v=").
> From my understanding, both methods should return the relevant values from
> the frozen node. The error occurs because of line 185 in JcrNodeResource.java
> {{Node content = node.isNodeType(NT_FILE)}}
> {{? node.getNode(JCR_CONTENT)}}
> {{: node.isNodeType(NT_LINKEDFILE) ? node.getProperty(JCR_CONTENT).getNode()
> : node;}}
> When the resource is looked up with a version modifier, the node type will
> not nt:file. Instead it is jcr:frozenNode with a property
> jcr:frozenPrimaryType set to nt:file. Therefore, the above code fails and
> will not use the jcr:content subnode, but the node itself. In my opinion, it
> would be better to change this to:
> {{{{Node content = (node.isNodeType(NodeType.NT_FILE) ||
> (node.isNodeType("nt:frozenNode") &&
> node.hasProperty("jcr:frozenPrimaryType") }}}}
> {{ &&
> node.getProperty("jcr:frozenPrimaryType").getString().equals(NT_FILE)))}}
> {{ ? node.getNode(Node.JCR_CONTENT)}}}}
> {{ : node.isNodeType(JcrConstants.NT_LINKEDFILE) ?
> node.getProperty(Node.JCR_CONTENT).getNode() : node;}}
>
> JcrResourceMetadata has the same issue (line 65):
> {{ if ( (!nodePromotionChecked) && node.isNodeType(NT_FILE)) {}}
> This could be changed to:
> {{ if ( (!nodePromotionChecked) && (node.isNodeType(NT_FILE) ||}}
> {{ (node.isNodeType("nt:frozenNode") &&
> node.hasProperty("jcr:frozenPrimaryType") }}
> {{ &&
> node.getProperty("jcr:frozenPrimaryType").getString().equals(NT_FILE)))) {}}
>
> As I'm still a newbie in Sling, I'm not sure if the proposed solution is
> completely right. At the moment, I use a ResourceDecorator for my project
> with these changes and this fixes my problem - but there might be a better
> way to solve this.
